My Honda PCX 125 Engine Screen Blackened and Warranty Cancelled

As a Honda PCX 125 owner, I was shocked to learn that my engine's screen had blackened and that my warranty had been voided. I requested a replacement but was denied due to "intense sunshine," an inexplicable reason. I was told that my engine should be serviced every 3000 km or 6 months, but I was never told that if I did not have maintenance every 6 months, my warranty would be voided. As a result, I had to purchase three new engines. This is a very serious situation that must be addressed. I believe that I should be given a replacement engine as well as compensation for all of the engines I've had to purchase and that Honda should be more upfront about their warranty requirements with customers.
